SPECIFICATION forming part of Letters Patent No. 317,093, dated May 5,188

Application filed December 2'1, 1884. (No model.)

To all whom it may concern:

Be it known that I, HUTsON B. OoLMAN, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, and State of Michigan, have invented a new and useful Wind-Engine, of which the following is a specification.

This invention relates to that well-known class of wind-engines in which power-transmitters are employed, consisting of swiveled reciprocating rods and pivotally-connecting pitmen, their use being to transmit rotary motion from the wind-wheel shaft having a swiveled bearing-support to a power-shaft having a stationary bearing-support.

It has for its object certain improvements in construction and arrangement designed to effect greater simplicity and utility and to facilitate the operation.

In the drawings forming apart of this specification, Figure 1 is a broken side elevation with parts in vertical section; Fig. 2, a view of parts in Fig. 1, looking from a point at the right of the latter figure; Fig. 3, a broken detail in enlarged perspective; and Fig. 4 is a cross-section on line 2 2 in Fig. 1, looking from a point above said line.

Referring to thedrawings and the letters marked thereon, A A represent the upper portion of a wind-engine derrick, in which the head B has swiveled bearings in the usual mannor to allow the wheel to shift to different points of the compass. I

The inner end of the wheel-shaft E is provided with a crank-disk, 0, having cogs around its periphery. Below the disk 0 is another crank-disk having a like cog-periphery, and supported by an axle connecting with the head B. In their operative relation with each other these two crank-disks c v constitute two meshing pinions. In suitable stationary bearingsupport below are two like cog crank-disks, c o, the disk 0 being connected with the power-shaft S.

The reciprocating rods consist of the tubular rod or and the rod h, located in the former in a manner to play vertically therein. The

tubular rod a is connected with the wrist-pin of the pinion c by apitman, c, (the pivot at n being rigidly secured to the rod a,) and is connected withthe other pinion, c", by a pitman, 0', the pivot at f being swiveled to the end of the rod a. v

The rod h has a rigidly'connected pivot, :20, extending outward through a vertical elongated slot in the tubular rod a,with this pivot 00 and the wrist-pin of piniono is connected a pitman, r. The lowerend of rod his pro vided with a swiveled pivot at f, and with this pivot and the wrist-pin of pinion o a pitman, r, is connected. The pivotal connections of the pitmen r r with the wrist-pins of the pinionso o are at such points on said pinions, as compared with the points of the pivotal connection of the pitmen c c with the pinions c c, that when the former are on their dead-centers, the latter are off their dead-centers, and vice versa, Fig. 2. The lower end of rod h plays through a guide-bearing, d. The upper portion of the tubular rod a has suitable bearings in the head 13 and the pendent tube thereof. The opposite ends of these rods a h are properly supported by onebeing within the other, Fig. 1. I

To obviate danger of the pivots at ff being thrown out of proper position by the turning of the reciprocating rods a h when the head B turns in its swiveled bearing, the swiveling collars of said pivots are provided with laterally-extended arms a z, slotted in the ends so as to play vertically on the stationary guide-bar g, Figs. 1 and 4.

In the operation, when the head B turns in its swiveled bearing, presenting the windwheel to different points of the compass, the

rods 11 h are turned in their swiveled connections at ff with said head. Thus said rods do notturn independently of each other, nor around each other, but turn together with the head on a vertical imaginary axis common to all said parts. The wind-wheel imparts rotary motion to the driving-shaft E and cog crankdisk 0, from thence to cog crank-disk o, causing the rod h to play vertically. This action imparts rotary motion to the cog crank-disk o, and as said disk meshes with the cogs of disks" the latter is thrown off of its dead-centers by the former. Rotary motion also being imparted from the crank-disk c to the disk 0 by means of the connecting-pitmen 0' and c and the verti- IOU cally-playing tubular rod a, the motion of said disk 0 in turn throws the the disk 1) off of its dead-centers.

Motion may be imparted from the'driven shaft S to other machinery by any means common to such devices. The means here shown are a pulley and belt, D, the latter being broken.

The construction of wind-engines and their operation beingjso Well understood, no further description is deemed necessary.

Having thus described my invention, what I claim as new is 1. In a mechanism for transmitting rotary motion from one shaft to another by means of swiveled reciprocating rods, the combination, with a driving-shaft and a driven shaft, the former having a swiveled bearing-support, and the latter having a stationary bearing-support, of cog crank-disks secured to each of said shafts, and like cog crank-disks revolubly supported by each of said bearing-supports in position to mesh with the cog crank-disks of the shafts, swiveled reciprocating rods, and pitmen connecting said rods with the cog crank-disks, substantially as set forth.

2. In a mechanism for transmitting rotary motion from one crankshaft to another by means of swiveled reciprocating rods and piv eled to said rod, all substantially as set forth. 7

3. The combination of the driving and driven shafts, swiveled reciprocating rods, pivotally-connecting pitmen, and a stationary guide-bar, the swiveled pivots having slotted laterally-extending arms adapted to play on said guide-bar, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.
